Description

technical field [0001] The invention belongs to the technical field of spacecraft ground flight control and support, and relates to an intelligent data analysis and decision support system for spacecraft rendezvous and docking flight control. Background technique [0002] Spacecraft engineering is a system engineering with high risk, high investment and high complexity. Spacecraft flight control is an important part of aerospace engineering. Space rendezvous and docking is a difficult and highly important task in spacecraft flight control. During the space rendezvous and docking process of spacecraft, two or more spacecraft complete the rendezvous and docking on the space orbit, and the relative speed and trajectory need to be controlled within Within a certain safety range, the correctness of the operating status of the relative navigation sensors and actuators during the rendezvous affects the safety of the operation. The above situation requires accurate flight control ...

AI Technical Summary

Problems solved by technology

[0008] However, the existing technical solutions mainly have the following problems: the method in technical solution 1) can only monitor the real-time status of flight control, and cannot estimate and forecast future events in advance, and has limited support for flight control decisions

The initial condition setting for the real on-orbit state of the flight mission in mathematical simulation is relatively cumbersome, and relevant variables need to be manually extracted from the real-time flight control telemetry system. There are situations where the preparation work efficiency is low and the operation speed is slow. It is helpful for flight control decision-making in emergency situations. limited

The accompanying verification of the target machine in technical solution 3) is usually verified a period of time in advance. This method can effectively simulate the state that is predicted in advance on the orbit, but it cannot be verified in time for the state caused by an emergency, and it is difficult to effectively provide information for decision-making. support
